  • BZX884C18V: Abnormal Zener diode clamping

    TI 认为已经解决
    Part Number: BZX884C18V Hello TI engineer, In my flyback power supply, the auxiliary winding voltage is rated 18V, but rises to 21V under heavy load. I tried a series resistor（2.5ohm） + Zener diode （BZX884C18V）clamp to limit the auxiliary voltage, but…
